Operands:
S : Timer for monitoring annunciator m: Time setting D: Annunciator device
Explanations:
1. Range of S : for SA/SX/SC T0 ~ T191; for EH/EH2/SV T0 ~ T199.
2. m can designate K1 ~ K32,767 (unit: 100ms)
3. Range of D : for SA/SX/SC S896 ~ S1023; for EH/EH2/SV S900 ~ S1023.
4. See the specifications of each model for their range of use.
5. Flags: M1048 (annunciator in action); M1049 (valid monitoring)
6. This instruction is used for enabling the annunciator.
Program Example:
If X3 = On for more than 5 seconds, annuniciator point S999 = On. Even X3 goes Off afterwards, S999 will still keep
On. However, T10 will be reset to Off and the present value = 0.

Explanations:
1. No operand.
2. This instruction is used for resetting the annunciator.
3. When more than one annuciators are On, the annunciator of smaller number will be reset.
4. This instruction adopts pulse execution instructions (ANRP)
Program Example:
1. If X10 and X11 = On at the same time for more than 2 seconds, annuniciator point S910 = On. Even X10 and
X11 go Off afterwards, S910 will still keep On. However, T10 will be reset to Off and the present value = 0.
